Lenovo ThinkPad T490s 8GB vs 16GB RAM in Kenya: The Upgrade That Matters
Quick answer: Buy the 16GB T490s if you multitask heavily or plan to keep it for years. Lenovo specifies soldered, non-upgradable memory for the T490s family, so verify the installed amount before paying.
A used ThinkPad T490s may look identical in photographs while carrying 8GB, 16GB or 32GB of memory. This is particularly important because Lenovo’s platform specification identifies soldered RAM rather than a normal removable memory slot. The cheaper option can therefore be a long-term limitation if your work changes.

Why soldered memory changes the purchase decision
Lenovo PSREF lists 8GB, 16GB and 32GB soldered configurations for the ThinkPad T490s, with no ordinary RAM expansion slots. A seller cannot safely promise a routine upgrade from 8GB to 16GB as if it were a desktop DIMM. Ask to inspect system information and the manufacturer machine type before purchase.
The SSD is a separate part of the decision: the T490s platform supports M.2 storage options, but the installed drive capacity and replacement compatibility should still be verified. More SSD space does not fix an insufficient RAM configuration.
How do 8GB and 16GB differ in ordinary use?
An 8GB machine may handle Word, email, moderate browsing and occasional meetings adequately. Multiple browser profiles, heavy spreadsheets, creative applications and several programs running together are more likely to expose memory limitations.
Sixteen gigabytes generally provides more headroom for the way professionals multitask, but it does not make the CPU a newer generation or add dedicated GPU capability. Compare the precise Core i5 model, display resolution and thermals when choosing between used units.
Is paying more for the 16GB version sensible?
The checked price difference is KSh 3,995. For someone who relies on many tabs, data-heavy files or a long working day, that is a relevant upgrade because the RAM is not normally replaceable. For occasional documents and a strict budget, 8GB may remain suitable.
Validate that the 16GB amount is installed rather than promised in a seller caption. Ask for a fresh system-information photograph, test all USB-C charging functions and verify the machine is free from BIOS or device-management locks.

Refurbished laptop inspection checklist
Ask for the full CPU model and serial/product number; test the screen, hinges, keyboard, ports, charger, Wi-Fi, microphone and webcam. Request a battery health report and SSD health check, plus the Windows edition and activation state. Verify cosmetic grade, return policy, warranty and availability of the exact specification advertised. Compare the total delivered price rather than just headline cost.
